# I’m unable to push the invoices to the IRP because it says the quantity must be in a regular expression. What should I do?

If the quantity has more than three decimal places, the invoice cannot be pushed to the IRP. This is due to a restriction in the IRP system, which enforces a regular expression format that typically allows a maximum of three decimal places.

Once the decimal place in the _Quantity_ field is updated, try pushing the invoices to the IRP again.

**Insight:** You will face a similar error if the _Item Rate_ has more than three decimal places. In such cases, you will need to update the _Item Rate_ in the invoice before pushing it to the IRP.
